Bug Description

hermes doctor reports ⚠ MiniMax (China) (HTTP 404) even though the MiniMax API is fully functional and all actual AI completions work correctly.

Root Cause

In hermes_cli/doctor.py, the health check for MiniMax (China) uses:

GET https://api.minimaxi.com/v1/models

However, the MiniMax /v1/models endpoint only accepts POST requests (it is a chat completions-style endpoint), not GET. Sending a GET request to this URL returns 404 page not found.

Verification

A direct POST to the chat completions endpoint works perfectly:

curl -X POST "https://api.minimaxi.com/v1/chat/completions" \
  -H "Authorization: Bearer $MINIMAX_CN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"MiniMax-M2.7","messages":[{"role":"user","content":"hi"}],"max_tokens":5}'
# → HTTP 200, valid response

But GET /v1/models returns 404.

Suggested Fix

For MiniMax (China) minimax-cn provider, either:

1. Skip the /models health check (set supports_models_endpoint = False for this provider, like OpenCode Go), OR
2. Use a POST-based health check — call POST /v1/chat/completions with a minimal request and check for 2xx response, OR
3. Document this as a known false positive in the doctor output

Option 1 is the simplest and matches the existing pattern used for providers that do not support the /models endpoint.

Environment

• Hermes version: 0.9.0 (latest main)
• Platform: macOS
• Provider: minimax-cn (MiniMax China)
• API endpoint: https://api.minimaxi.com/anthropic
